Technical Field

[0002] The existing traditional technology does not have suitable tooling to simulate the effect of wire embedding and copper bar bending in the absence of an iron core. In corporate production, when developing the first batch of customers or new models of products, customers often only provide coil drawings, number of slots and diameters due to confidentiality of drawings. In previous cases, after receiving an order, marketing would purchase a wind turbine rotor material in advance for internal process verification. It is very likely that after purchasing the material, it will be found that the process requirements cannot be met and production cannot be completed. This situation will affect the company's reputation and waste material costs (the material cost of wind turbine rotors is relatively expensive). In addition, there is also the purpose of verifying whether the customer's drawings are correct and whether the product design is reasonable. Utility Model Content

[0007] Furthermore, three screw rods are provided, and the three screw rods are distributed and fixed on the test panel in a triangular shape.
[0008] Furthermore, an anti-slip structure is provided at the notch of the embedding groove.
[0009] Further, the anti-slip structure comprises an anti-slip cone block, which is located at the notch of the embedding groove and is integrally formed with the test embedding plate.
[0010] Furthermore, three support columns are provided, and the three support columns are distributed and fixed in a triangular shape between the two test panels.
[0011] Furthermore, the support column and the test panel are connected by welding.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model sets a test embedding plate, and positions and fixes two test embedding plates by positioning columns and a plurality of supporting columns, and opens a plurality of embedding grooves on the test embedding plate, so that the copper bar can be embedded in the embedding grooves to simulate the embedding effect and the copper bar bending effect, so as to check the curvature, bending angle, straight line length, corner size of the internal copper bar bending, whether the embedding of coils in the same slot has interference, and other effects on subsequent processes, so as to predict problem points in advance, reduce unnecessary investment, and verify the feasibility of the project; at the same time, the tooling structure is simple, the manufacturing cost is low, and the test cost can be greatly reduced.
